Jacobs v Baumann NO and Others

The respondents, heirs to a deceased Swiss national’s estate, instituted action in the Cape High Court for repayment of a long‑outstanding loan made by the deceased to the third appellant close corporation. At the time summons was issued, the action was brought in the name of the estate represented by Mr Wirz, who had been appointed by a Swiss court as ‘representative of the heirs’/administrator. His appointment was later set aside by a Swiss appellate court for procedural defects. Thereafter, Mr Baumann was validly appointed as representative of the heirs, and the respondents sought to substitute him for Wirz in the South African proceedings and to join an omitted heir. The appellants opposed the substitution, arguing that Wirz’s appointment was unlawful, rendering the summons a nullity and that substitution would prejudice them by depriving them of a prescription defence.

The appeal was dismissed with costs, including the costs of two counsel.

The case clarifies South African law on the validity of proceedings instituted by an executor or estate representative whose appointment is later set aside, confirming that such acts are valid until the appointment is judicially withdrawn. It also affirms that substitution of a duly appointed executor does not constitute the addition of a new party and does not interrupt or prejudice substantive defences such as prescription.
